WILLIAM I-I. CASSELBERRY, OF WILLIAIWISPORT, PENNSYLVANIA.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent 0.602,553, dated April 19,1898. Application 1ed October 19,1897. Serial No. 655,691. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM HENRY CAs- SELBERRY, a citizen of the UnitedStates, residing at W'illiamsport, in the county of Lycoming and Stateof Pennsylvania, have invented certain new and useful Improvements inWindow-Screens and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has relation to windowscreens.

The object is to equip each sash with a screen which when not desired isconcealed within a casing and which may be easily engaged with the sashand drawn across the opening of the window-frame when desired.

W'it-h this object in view the invention consists of certain features ofconstruction and Y combination of parts which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure 1 is a perspective view of awindow-frame embodying my invention. Fig. 2 is a longitudinal sectionalview; and Fig. 3 is a fragmentary view of one of the screen-casings,illustratin g the j ou rnal-block for the screen-roller.

In said drawings, l denotes a window-frame, and 2 and 3 the lower andupper sashes, respectively. At the upper and lower ends of thewindow-frame are screen-casings 4, having removable fronts 5. the endsof these casings are provided with transverse guideways 6,which receiveblocks 7, that support spring-rollers 8. These rollers S are providedwith exible screens 9, the free ends of which are provided with plates10, having openings 1l. The upper sash has an arm 12, that projectsinwardly and is curved to form a bearing 13.

14. denotes an operating-rod which has its upper end journaled in saidbearing and its lower end extending downwardly through a guide-eye 15and formed with a handle 16. The extreme upper end of this rod isprovided with a crank 17.

18 denotes a catch which is pivoted to the upper cross-piece of theupper sash and is adapted to pass through the opening in the platesecured to the free edge of the screen.

19 denotes a link that connects the pivoted catch to the crank of theoperating-rod. When it is desired to lower the upper sash and at thesame time to draw down the screen The inner sides of and cover theopening in the frame, the operating-rod is turned in its bearings, so asto work the catch into the slot of the plate on the lower end of thescreen, and while drawing down upon the rod the upper sash will belowered and simultaneously draw down the screen. If, however, it isdesired to simply lower the upper sash, this may be accomplished bydrawing down upon the operatingrod. It will thus be seen that the sashmay work independently of the screen.

The lower cross-rail of the lower sash is provided with a recess inwhich is pivoted a combined catch and pull`20, which is adapted to beengaged with a strip at the end of the lower screen for the purpose ofdrawing the screen up when desired. A cam 2l may be employed for thepurpose of holding the lower sash in its adjusted position.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and advantages of myinventionwill be readily understood without requiring further explanation.

If not desired, the screens maybe allowed to remain in their casings,and when desired to be used may be easily connected with the sashes andwill be lowered and elevated in unison with said sashes.

Should it be desired to replace the screens should they become worn ordamaged, the front pieces of the casings are removed and the slides thatsupport the spring-rollers are withdrawn, thus enabling new screens tobe put in place.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination with a window-frame, a screen-casing, a screen-roller inthe screencasing, a screen secured to the roller, the upper sash, a barextending inwardly from the upper sash, a catch pivoted to the uppersash, an operating-rod carried by the bar, and a link connecting theoperating-rod to the catch, whereby said catch may be caused to engagethe screen and draw it down in the act of lowering the upper sash,substantially as set forth. Y

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
